Growth and Optical Properties of Li13Nd(GeO4)4 Single Crystal

Abstract
In this paper, single crystals of Li13Nd(GeO4)4 are grown by the Czochralski method. The unit cell dimensions and the crystal system are determined by an X-ray diffraction method. The principal refractive indices, n a, n b and n c and the temperature dependence of birefringences, n c-n b, n c-n a and n a-n b, over the temperature range from room temperature to 500degC are measured. A fluorescence spectrum at around 1.06 µm is observed, and strong fluorescence is detected.
